5) A cue ball .17 kg travels at 2.16 m/s it hits an eight ball .156 kg which is initially at rest after the collision the cue ball continues forward at .963 m/s how fast is the eight ball traveling?

6) A 2400 kg truck traveling at 27.45 m/s has a head on collision with a 1300 kg car traveling at 37.54 m/s they collide and stick together what is the final velocity?

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
